IMPROVEMENT lN noM'EsTrc SPINNING-WHEELS.

Specification forming part of Letters Patent No. [93,562, dated July 24,1877; application filed March 24, 1877.

To'all whom it may concern:

Be it known that we, JOHN ALLEN SMITH and ELBERT S. SMITH, of Pond Fork,in the county of Jackson and State of Kentucky, have invented a new andvaluable Improvementin Domestic Spinning-\Vheels; and we do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representa' tion of a side elevation ofour spinning-wheel; and Fig. 2 is a side elevation, with one of the siderails removed, showing the mechanism in position. Figs. 2%, 3, 4, 5, and6 are detail views thereof.

This invention relates to spinning-wheels and devices in combinationtherewith; and it consists in the construction and arrangement ofcertain mechanism for moving the spindlecarriage backward and forward,and for alternately catching and releasing the same, substantially ashereinafter set forth.

In the accompanying drawings, A designates the main frame or bench of mymechanism, which affords a long guideway, B, on one side of one end ofwhich a circumferentiallygrooved spinning-wheel, O, is journaled. Ineach end of said guideway is a slotted block, D, which has twoinwardly-extending lips, E, that serve as bearings for a small shaft, F,which is provided with a large grooved pulley, G, and two smallergrooved pulleys, H, each trio of pulleys being connected together so asto turn as one piece. of the above devices is the same at each end ofsaid guideway, except that the farther one.

The construction fixed pieces in the end of guideway B by means ofscrews K and small blocks K.

L designates a spindle-carriage running in said guideway B, and providedwith two small standards, L L, in which a spindle, M,

is journaled. Said spindle is provided on the outside of said standardswith collarsl l, which keep it in place, collar 6 being made in onepiece with a small pulley, Z. An endless band or cord, N, passes aroundsaid small pulley Z and. also over the two large pulleys G. Thetraveling of this band rotates said spindle so as to twist the thread,and also moves said carriage and spindle in said guideway toward theoperator.

O designates a fork or bifurcated block, which is pressed down into arecess, 0, in the top of said carriage, at the nearer end thereof, by aspring, P; and Q designates a similar fork or bifurcated block, which ispressed up into a recess, Q, at the bottom of the farther end thereof,by a spring, R. Band or cord J passes over said carriage under fork O,and under said carriage over fork Q; Another line or thickness of saidband or cord J runs over and under said carriage by the side of saidforks or bifurcated blocks. Said forks will allow said cord or band topass through them; but the knots or enlargements jj will not thus passeither fork until the bearing end of spring P or R is forced away fromsaid carriage, so as to increase the open; ing between the forked blockpressed by said spring and the carriage. This is automatically effectedat the nearer end of the guideway B by means of a fixed arched bar, S,which engages with an upwai dly-inclined extension, P, of spring P, andat the farther end by a fixed cross-bar, S, which engages with thedownwardly bent or inclined extension R of spring R. Said extension Rhas a catch, 1", formed in its upper side, which springs behind saidcross-bar S, and locks said carriage for a time at the farther end ofits course. Said carriageis released by a bifurcated tripping-lever,T,which is pivoted on the top of guideway B, and adapted to trip, by itslower end, catch r by depressing extension B. This action takes placewhen said tripping-lever is raised into a vertical position, it beingordinarily inclined toward spinningfwheel O. This is effected when'oneof said knots j is drawn backward against the bifurcated upper end ofsaid tripping-lever; but when said cord J travels in its usual directionsaid knots ride up over the narrow part tof the cleft in the upper partof said tripping-lever, and pass freely through the broader upper part tof 'said cleft or slot. On the top of said carriage is a small forkedcatch, U, which is inclined toward said spinning-wheel, so that saidknots may pass freely in their usual direction, but will engage withsaid catch and move said slide when traveling in the opposite direction.V is a small forked upright, which supports a part of cord J at thepoint where the latter is crossed.

The operation of this machine is as follows: The carriage L being in itsnearest position to the operator, wheel 0 is turned to the right untilthe knot j on band J (said knot being in front of knot j in thedirection of their usual motion) engages with lower fork or block Q, andcarries said carriage toward the farther end of guideway B. Whenextension R comes into contact with cross-bar S it is forced downward,carrying block or fork-Q down with it and releasing knot j. Knots j andj then pass freely through said fork Q without moving said carriage, andup over one of said small pulleys H. As said band-travels the knots passfreely through forked tripping-lever T and forked catch U; but when saidknot 3' reaches upper bifurcated block or fork 0 it cannot pass. Theother knot, j, is now barely through said bifurcated trippinglever, andsaid carriage is held, as stated, by catch 1 and cross-bar S. The wheel0 is then slightly turned in a reverse direction, and the reversedmovement of said band causes said knot j to raise said tripping-leverinto a vertical position, thereby freeing said carriage. By turning saidwheel in the usual direction said carriage is then carried by band Ntoward the nearer end of said guideway B, and it does not stop untilafter arched bar S'has raised extension P and block I or fork 0, so thatknots j j may continue their movement unimpeded.

The doubling of the small pulley H and the band or cord J allows theknots j j to make one entire journey from end to end of the guidewaywithout moving the carriage L, so

that spindle M is rotated for a time without being moved otherwise. Thisrotation twists the thread suitably. Catch U, by engaging with knotj,prevents band or cord J from being made to travel too far backward inreversing itsmotion for'the purpose of freeing said carriage, asdescribed.

What we claim as new, and desire to secure by Letters Patent, is-

l. The combination of a sliding spindle-carriage with cords or bands,which draw said carriage toward the operator, and also rotate saidspindle, substantially as and for the purpose set forth.

2. The combination of a sliding spindle-carriage with an endlesstraveling band extendin g from end to end of the guideway, and providedwith knots for moving said carriage and pulleys at each end,substantially as and for the purpose set forth.

3. The combination of a sliding spindle-carriage, having aspring-pressed fork at each end, with a knotted traveling cord or bandand devices, substantially as described, at the ends of the guideway,for forcing said forks away from said carriage, substantially as and forthe purpose set forth.

4. The combination of bifurcated trippinglever T, having cleft t t, withband or cord J, having knots j j, cross-bar S, and carriage L, withextension R, having catch 1", substantially as and for the purpose setforth.

5. The combination of slotted lever T, knotted cord J, cross-bar S,extension R, spring R, fork Q,'and carriage'L, substantially as and forthe purpose set forth.

6. The combination of spindle-carriage L, provided with inclinedbifurcated catch U, and cord or band J, having knots or enlargements jj, substantially as and for the purpose set forth.

7. The combination of arched bar S with inclined extension P, spring'P,and fork or bifurcated block 0, supported by carriage L, substantiallyas and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
